GAS-STOVE.

SPECIFICATION forming part of Letters vPatent No. 293,698, dated February 19, 1884.

Application ined JulyY 31,1883.` (No modem.

' To all 'Iv/wm, il: may concern:

. with an upper baking-Oven and a lower roasting or cooking chamber, of a gasburner arrangedbetween them, and removable non-conducting shields or partitions adapted to be placed. in said oven and chamber above and below the burner. When the oven is to be used, a shield or partition is to be placed immediately below the burner in the roastingchamber, to keep the heat from the said chamberand when said chamber is to be used for roasting or other purposes a shield or partition is placed inthe bottom of the oven, to prevent the radiation of heat upward.

The invention also consists in the combination, in a stove, with a chamber containing a burner anda superposed oven surrounded by heating dues or spaces, of a lateral extension furnished with a pot hole or holes and a damper for directing the heat from said burner through said lateral extension or through the flues or spacesaround said oven.

The invention also consists in the combination, with the aforesaid burner and an oven arranged abovethesame and surrounded by heating-spaces, .of aylateral extension provided with one` or morey pot-holes and dampers, whereby the heat may be caused to pass directly upward around the oven, or vrst through the lateral extension and then up and around the oven.

The invention also consists in the combination, with a chamber containing` the aforesaid bu'rner,whicl1 I may term the main burner,77 of a lateral extension provided with one or Inore pot-holes, and through which the heat may be passed from the main burner when the full heat from said burner is not required for cooking above or below it, and an auxiliary burner arranged in the extension for use when the full heat from the main burner is required elsewhere, or when it is not desired to use thev main burner.

The invention also consists in the combination,with the aforesaid auxiliary burner, of an air damper or register in the bottom 'of the extension, which may be opened when it is desired to use the auxiliary burner, but which is closed when the extension is to receive heat from the main burner. VThe stove may have two or more of the above-described lateral extensions, and each extension mayhave as many auxiliary burnersas it has pot-holes.

The invention also consists in novel features i-n the construction of the lateral extensions aforesaid, some of which features are especially desirable when an extension has two auxiliary burners, for the purpose of hastening the escape of the waste products of oom-l bustion from one burner, which only is then in use.

The invention also consists in other features of construction and combinations of parts hereinafter described and claimed. I

l In the accompanying drawings, Figure l is a vertical section of a stove embodying my invention. Fig. 2 is a sectional view, upon a larger scale, of one of the auxiliary burners. Fig. 3 is a sectional view of one of the nonconducting removable shieldsv or partitions. Fig. 4 is a vertical section on the dotted line x m, Fig. 1,the main burner alone being shown in exterior elevation. Fig. 5 is a View of one of the lateral extensions,looking from the side usually j oine'd to the stove. Fig. Gis a perspective View of the lateral extension detached from the stove, and with the rtop removed.

Fig. 7 is a perspective view, showing an arrangement of dampers hereinafter described. Fig. 8 is a horizontal section on the dotted line y y, Fig. 1, a portion of the top of the right-hand lateral extensions being broken IOO be constructed of cast or sheet metal, as may be most suitable. In the main portion of the stove are constructed a lower chamber, A, for roasting or cooking, and an upper bakingoven, B, and between them is arranged ahorizontal gas-burner, C, of ordinary construction.

D designates the main gas-pipe, and D designates branch pipes leading to the burner C, and of which two are shown in Fig. S. In each branch pipe D is an air-inlet, a,through which air enters to mix with the gas. In lieu of one large burner, C, I may use two or more smaller burners arranged side by side, and capable of being used separately or together. The chamber A and oven B are provided on their inner sides with ledges or supports b, whereon the shelves or racks may be placed. Vhen it is desired. to get as strong heat as possible in either the oven B or chamber A,it is of course advantageous to prevent the radiation of heat into the chamber Aor oven B; and to this end I employ removable partitions or shields A B, which are adapted to be placed on the ledges b, as shown in the case of the shield A', Fig. l. These shields may be constructed of two sheets of iron with a layer of asbestus between them. rIhe shield A prevents a large proportion ofthe heat from being directed down into the chamber A and radiated outward from the walls thereof, and so produces a more intense heat in the oven B.

rlhe shield B for the oven B is shown in Fig. 3; and when it is desired to roast or do other cooking in the chamber A, I remove the shield A therefrom and put the shield B at the bottom of the oven B, as shown by dotted lines in Fig. l.

In the bottom c ofthe oven B, I form a pothole, d, and when the oven is not desired to be used I may place a kettle, E, or any vessel, on the hole d, and heat it very rapidly. j

On the two sides and back of the oven B are heating-spaces e, andthe hot products of combustion pass upward around the oven B, thence under a plate, c', (shown in Fig. 4,) which plate causes them to pass over the top of the oven, and thence over said plate to the outlet-pipe el. (Also shown in Fig. 4.) At the front edge of the plate c the edge c is turned upward, so as to prevent the heavy products of combustion which may settle on the plate c from returning. below said plate, and to carry away said heavy products the outlet e2 is made slightly lower than the plate c', as shown in Fig. 4.

At one or each side of the main portion of the stove I attach a lateral extension, F` wherein are one or more pot-holes, d. As shown in Figs. l and S, there are extensions 011 the right and left sides of the stove, and I may, if desired, arrange a third extension at the back, as shown by dotted lines in Fig. l0. As shown in Figs. l and 8, each extension has two pot-holes, d'; but one or each extension may have four pot-holes, d, as shown in the case of the right-hand extension in Fig. l0. In each extension F there is a lateral partition, f, which extends nearly but not quite to the outer side thereof, leaving a passage or aperture, f, around its outer edge, for the passage of the products of combustion above said partition when they return inward. The space below the partition is divided by an upright partition, f Z, between the pot-holes, and, as best shown in Fig. l, the pot-holes are in the partitionj', as well as in the top of the eX- tension, and the well ot the kettle E or boiler El projects downward through the partition f. l'he extension F may be supported by brackets F', and where a long extension is used, as shown at the right hand of Figs. E) and l0, I may support the outer end of the extension by a leg, F2, as shown in Fig. 9. The space below the extension may then be inclosed and fitted with shelves f i, (shown dotted in Fig. 9,) so as to serve as a hot closet. A second stove may be placed by the-side of the iirst, with the extensions of the two meeting, as shown dotted in Fig. 9, and the space below the meeting extensions may be vlitted up to serve as a hot closet.

At the junction ot' each extension F with the main portion of the stove are dampers y g', attached to a common shaft or spindle, g, which projects through the front of the stove, and is provided with a handle, y, for turning it. rlhe dampers r/ control the passage upward tothe sideheating spaces or ilues,.c, ofthe oven, and the dampers y control the passage into the extension F below the partition f. Vhen the heat from the burner C is not all otherwise required, I turn the dampers g r/ into the positions shown at the left hand of Fig. l, thus opening the passage into the extension F, and closing by the damper f/ the passage directly upward into the flue or space c. The hot air and products-of combustion will then pass through the extension under the partition f, through the aperture j", and back over the partition f, to the fine c, and thence upward. rlhe hot products of combustion come in contact with the bottom ofthe kettle E in their passage outward, and impinge around the side of the kettle-well in their passage inward.- The heavier products of combustion will settle on the bottom of the extension, and I provide checks or guards Il., (shown in Figs. l and 4,) which form pockets to catch and retain these heavy products of combustion, and prevent them from getting round the burner C and impeding combustion.

Vhen all the heat from the burner G is required elsewhere, the dampers gg are turned into the positions shown at the right of Fig. l, to close the-passage into the extension and open the passage directly into the heatingV lue or space c. To the end that the exten- In each The aux- IOO IIO

iliary burners are'of well-known' form, and consist of a hollow annular ring, fi, provided with perforations, as best shown in Fig. 2. In the burners C' (shown in the left-hand extension in Figs.-v l and 8) the branch pipes D2 deliver the gas directly into the hollow ring f5,- but in the burners shown .in the right-hand extension in said gures, and in Fig'. 2, the gas is delivered by the pipes D2V at the center, and passes through a passage, t', to the ringe' of the burner. The auxiliary burners C may be cast complete in themselves; but I prefer to form the rings or shells t' without bottoms, and' attach them to the bottoms of the extensions, the said bottoms of the extensions forming the bottoms of the burners, as shown in Fig. 2.

In order to supply thenecessary amount of air for the combustion in the burners C', I form holes or apertures i2 on the insideof the rings'i, and perforations i" on the outer side of the said rings. The passage of air through the openings t2 is is controlled by register plates or valves G, which are placed on the under sides of the extensions, and are adapted to be turned so as to allow air to enter when the auxiliary burners C' are used, and so as to cut oft' the entrance of air when the extensions are heated by the main burner C. Atthe back l of the stove and on oppositesides of the oven are escape-dues j for the produc-ts of combustion from the vauxiliary burners, and each flue is controlled by a damper, j.- When the aux. iliary burner O which is nearest the front of the stove is in operation, the other pot-hole d in that extension is closed bya cover shaped like the well of akettle, and adapted to extend through the hole in the partition f.v Such a cover is shown in Fig. ll. The Waste prol ducts of combustion from the burner in use At the back ofthe ovenB is a hinged damper, Z, which, by means of a handle, Z, (shown in Figs. 4 and 8,) may be opened or closed. In lieu of ahinged damper at the-back, I may emplay a ixed plate provided with perforations Z2. (Shown dotted in Fig. 8.)

As shown in Figs.14, and 8, the dampers Z and g are all operated separately; but in order to avoid going round to the back of the stove when the back damper is to be opened, Imay provide the shaft g2 of one of'the pairs of dampers g g with an arm, g, which extends under the back damper, l, as shown in Fig. 7, and when the said'shaft is turned to shift the dampers g gcarried by it, it will also raise the damper Z by means of .the arm g4. o

The chamber A and oven B are provided at the front with the usual-doors, AQ'BZ, toafford access to them., Y y
